Boron doped cement and concrete

A concrete composition comprising:

• a cement paste, a fine aggregate, and a coarse aggregate, wherein the cement paste includes homogeneously dispersed cement particles, water, and boron particles, wherein the boron particles comprise a boron compound, wherein the boron particles have a largest least dimension of about 1 micron to 100 microns, wherein the boron particles are dispersed homogeneously in the cement paste, wherein the boron content in the cement paste is about 0.5-80 kg/m3, wherein the boron compound is one of the following:
• 1) an organoboron compound;
• 2) a borate ester or their hydrated form;
• or 3) an ionic borohydride.

A concrete composition comprising:

• fine aggregate particles and coarse aggregate particles, wherein the fine aggregate particles and coarse aggregate particles each have a neutron shielding coating comprising a boron compound, wherein the boron compound is part of boron particles that have a largest least dimension of 1 micron to 100 microns, wherein the fine aggregate particles are selected from the group consisting of:
• natural or synthetic sand, crushed stone, and gravel, wherein the coarse aggregate particles are selected from the group consisting of:
